JAXA Supercomputer System Annual Report February 2023-January 2024 Report Number: R23EACA46 Subject Category: JSS Inter-University Research PDF Responsible Representative: Kiori Obuse, Associate Professor, Okayama University Contact Information: Kiori Obuse(obuse@okayama-u.ac.jp) Members: Yusuke Hagimori, Kiori Obuse Abstract Two-dimensional barotropic model on a rotating sphere is one of the simplest mathematical models describing the dynamics of planetary atmospheres. The two-dimensional turbulence shows the spontaneous formation of large-scale zonal flows similar to those seen on giant gas planets such as Jupiter. However, this mechanism・・・<<read more>>
